@ halogens. Ive seen coffee grown under halogens. Flouros blow that out of the water, and HID blows flouros out of the water, so I can imagine the shock you must have endured with the new lights.
Its a hobby ive read much about but have very little indulgence in. Someday when the situation and conditions are right I guess. :hs:
Indoors >>>>>>>> outdoors. Unless we are talking canadian medical outdoors. That shit is fucking sick. Those canadians love their coffee, and since there are no legalities, they can be tended to out in the open in large kegtub like containers, with an optimal soil and watering regimen so that its almost as controlled as an indoor setup.
